How EssayHero Assesses Cambridge IGCSE Essays
Full transparency on our criteria, scoring, and AI prompt for 0475 Literature and 0500 Language
Everything on this page is read directly from the configuration and prompt text that the AI uses when assessing a Cambridge IGCSE essay. This is not a simplified summary or marketing copy — it is the actual production system, rendered for inspection. Cambridge mark schemes are publicly available, and we align with them directly.
Syllabuses Covered
EssayHero supports three Cambridge IGCSE assessment types across two syllabuses. Each uses different criteria, mark allocations, and level descriptors — all drawn from official Cambridge Assessment mark schemes.
3 criteriona — total 25 marks
1 criterion — total 25 marks
2 criteriona — total 40 marks
0475 English Literature — Assessment Criteria
Literature essays are assessed against three criteria mapped to Cambridge's four Assessment Objectives (AO1-AO4). The total score ranges from 0 to 25 marks.
Detailed knowledge of content, understanding of meanings and contexts, informed personal interpretation with supporting evidence
0–15 marksSensitive personal response, independent thinking, originality of ideas, genuine engagement with the text
0–5 marksRecognition and appreciation of writers’ use of language, structure and form to create and shape meanings and effects
0–5 marksTotal: 0–25 (sum of three criteria)
0500 Directed Writing — Assessment Criteria
Directed Writing (Section A, Question 1) uses a single integrated Writing scale covering all five Assessment Objectives (W1-W5). The total score ranges from 0 to 25 marks.
Style (W1), structure (W2), vocabulary (W3), register (W4), and spelling/punctuation/grammar accuracy (W5)
0–25 marksSingle criterion assessed holistically across W1 (Style), W2 (Structure), W3 (Vocabulary), W4 (Register), and W5 (Accuracy).
0500 Composition — Assessment Criteria
Composition (Section B) is assessed against two criteria. The total score ranges from 0 to 40 marks.
Articulation of experience and ideas, organisation for deliberate effect, appropriateness to purpose and audience, engagement of reader
0–16 marksVocabulary range and precision, sentence variety and control, register appropriateness, spelling, punctuation, grammar accuracy
0–24 marksTotal: 0–40 (Content & Structure + Style & Accuracy)
Level Descriptors
These are the detailed descriptors the AI uses to place each criterion within the appropriate level. Cambridge uses six levels (Level 1 to Level 6) across all three assessment types. Select a syllabus below to view its descriptors.

Task RequirementsRequired
Cambridge IGCSE 0475 Assessment Objectives and task expectations
Cambridge IGCSE 0475 Assessment Objectives
The candidate's literary essay is assessed against these four Assessment Objectives,
grouped into three marking criteria:
Response to Text (AO1 + AO2) - 15 marks
AO1: Knowledge of Content
- Demonstrate detailed knowledge of the literary text

Personal Engagement (AO4) - 5 marks
AO4: Personal Response
- Communicate a sensitive and informed personal response
- Demonstrate independent thinking rather than rehearsed answers
- Show genuine engagement with the text and its ideas
- Go beyond surface reading to explore deeper significance
Language Analysis (AO3) - 5 marks
AO3: Language, Structure and Form
- Recognise how writers use language for effect
- Analyse structural choices (e.g., narrative perspective, time shifts, contrasts)
- Appreciate how form contributes to meaning (e.g., sonnet form, dramatic irony)
- Discuss the impact of specific techniques on the reader
Task-Specific Guidance

Scoring CalibrationRequired
Calibration guidance for consistent Cambridge IGCSE Literature marking
Scoring Calibration Guidance
Applying the Mark Scheme
- Best Fit Approach
- Read the response as a whole before awarding marks
- Assess each criterion (Response to Text, Personal Engagement, Language Analysis) independently
- Not every descriptor needs to be met exactly for a given band
- Award the mark that best reflects the response's quality for each criterion
- Using the Full Mark Range
- Within each band, use the full range of marks available
- Top of band: response meets all/most descriptors convincingly
- Middle of band: response meets most descriptors adequately
- Bottom of band: response just meets the descriptors
- Borderline Decisions
- When in doubt between bands, consider the distinguishing features
- Give benefit of doubt for genuine attempts at sophistication
- Consider which set of descriptors better captures the response overall
Criterion-Specific Calibration
Response to Text (15 marks):
- Knowledge must be accurate and relevant, not merely extensive
- Understanding goes beyond paraphrase to interpretation
- Evidence should be integrated, not bolted on as afterthought
- Level 6 requires perceptive, not just correct, understanding
Personal Engagement (5 marks):
- Personal response must be genuine, not formulaic
- "I think the writer..." is not automatically personal engagement
- Original insight is valued more than rehearsed critical opinion
- Level 6 requires thinking that genuinely illuminates the text
Language Analysis (5 marks):
- Feature-spotting without explaining effect = Level 2-3 maximum
- Analysis must explain HOW and WHY language creates meaning
- Accurate use of literary terminology adds precision but is not sufficient alone
- Level 6 explores effects with genuine insight and perceptiveness
Common Calibration Points
- Plot retelling caps achievement — Responses that primarily retell the story cannot score above Level 3 on Response to Text
- Assertion without evidence — Claims without textual support limit Response to Text to Level 3
- Feature-spotting without analysis — Identifying techniques without explaining effects limits Language Analysis to Level 2-3
- Formulaic responses — Answers that follow a template without genuine engagement cap Personal Engagement at Level 3
- Alternative interpretations — Credit valid readings supported by evidence, even if unconventional
- Ambition is rewarded — An ambitious but imperfect analysis scores higher than a safe but superficial one

Level Descriptors - CompositionRequired
Cambridge IGCSE 0500 Level 1-6 descriptors for Composition
Cambridge IGCSE 0500 Level Descriptors - Composition

Scoring CalibrationRequired
Calibration guidance for consistent Cambridge IGCSE marking
Scoring Calibration Guidance
Applying the Mark Scheme
- Best Fit Approach
- Read the response as a whole before awarding marks
- Identify which level descriptor best matches the overall quality
- Not every bullet point needs to be met exactly
- Award the mark that best reflects the response as a whole
- Using the Full Mark Range
- Within each level, use the full range available
- Top of level: response meets all/most descriptors fully
- Middle of level: response meets most descriptors adequately
- Bottom of level: response just meets the descriptors
- Borderline Decisions
- When in doubt between levels, look for distinguishing features
- Consider which set of descriptors better captures the response
- Give benefit of doubt for positive qualities demonstrated
Level Boundary Indicators
Level 6 vs Level 5:
- Level 6: "Highly effective", "sophisticated", "subtle meaning"
- Level 5: "Effective", "secure", "wide range"
- Key distinction: Level 6 shows exceptional control and sophistication
Level 5 vs Level 4:
- Level 5: Consistent effectiveness, wide range
- Level 4: Sometimes effective, adequate range
- Key distinction: Level 5 is consistently strong; Level 4 is uneven
Level 4 vs Level 3:
- Level 4: Some effectiveness, generally accurate
- Level 3: Inconsistent, simple vocabulary, frequent errors
- Key distinction: Level 4 shows competence; Level 3 shows effort but limitations
Level 3 vs Level 2:
- Level 3: Meaning clear despite awkwardness, some awareness
- Level 2: Limited vocabulary, not well sequenced, persistent errors
- Key distinction: Level 3 communicates adequately; Level 2 struggles
Level 2 vs Level 1:
- Level 2: Limited but coherent attempt
- Level 1: Expression unclear, impedes communication
- Key distinction: Level 2 has some organisation; Level 1 is very weak
Common Calibration Points
- Accuracy alone does not determine level - A technically accurate but simple response may still be Level 3-4
- Ambition is rewarded - Attempted sophistication with minor errors scores higher than safe but limited writing
- Content and language are interconnected - Strong ideas expressed poorly, or weak ideas expressed well, both limit achievement
Feedback RulesRequired
Cambridge IGCSE 0500 feedback format and style guidelines
Feedback Structure Requirements
Per-Criterion Feedback (JSON Format)
For each criterion, provide:
- A score (appropriate to the criterion's mark range)
- 2-3 specific strengths with evidence from the essay
- 2-3 specific areas for improvement with examples
- A concise overall comment
Paragraph-Level Analysis
For each paragraph, provide:
- writing (for Directed Writing) OR content_structure and style_accuracy (for Composition)
- Specific textual evidence for observations
- Actionable improvement suggestions
Feedback Style Guidelines
Be Specific:
✓ "The phrase 'a cacophony of clattering dishes' effectively evokes the atmosphere of the restaurant" (Level 5-6)
✗ "Good vocabulary" (too vague)
Reference the Mark Scheme:
✓ "This demonstrates 'wide range of vocabulary, used with some precision' (Level 5)"
✗ "Nice word choices"
Suggest Improvements Constructively:
✓ "To reach Level 6, consider varying sentence openings—currently 4 of 6 paragraphs begin with 'I'"
✗ "Too many sentences start the same way"
Balance Praise and Critique:
- Lead with strengths before addressing weaknesses
- Frame improvements as opportunities, not failures
- Acknowledge attempts at sophistication even if not fully successful
Cambridge-Specific Feedback Notes
- Assessment Objective References
- Reference W1-W5 where relevant
- Help candidates understand which skills to develop
- Level-Based Language
- Use Cambridge's own terminology (e.g., "engaging", "effective", "sophisticated")
- Quote descriptors when explaining marks
- Positive Marking Philosophy
- Focus on what the candidate HAS achieved
- Suggest what would move them to the next level
- Avoid language that sounds like deduction
- British English
- Use British spelling and conventions in feedback
- Note if candidate has inconsistent spelling conventions

Writing Tips
Guidelines for generating high-impact writing tips
High-Impact Writing Tips
Generate 3-5 writing tips that would most improve this essay's score. Focus on changes that would meaningfully move the criterion scores.
Each tip should be:
- Score-impacting: Would an examiner give a higher score if the student made this change?
- Specific: Reference actual content from the essay
- Actionable: Tell the student exactly what to do
- Prioritised: Most impactful tip first
- Criterion-linked: Name which criterion the tip addresses (e.g., "To improve your Content: ..." or "This would boost your Coherence & Cohesion: ...")
Categories:
- content: Ideas, relevance, creativity, engagement
- language: Vocabulary, grammar, sentence variety
- structure: Organisation, paragraphing, coherence
- style: Tone, register, voice
Examples of good tips:
- "Strengthen your conclusion by restating your main argument — this would improve your Content as it currently ends abruptly"
- "The phrase 'very important' appears 4 times — vary with 'crucial', 'essential', or 'vital' to raise your Language and Style mark"
- "Add sensory details to bring your story to life — describe what characters see, hear, or feel to boost Content engagement"
- "Your argument lacks specific evidence — add examples or statistics to strengthen your Task Response"
What We Cannot Do
EssayHero is designed for formative feedback between drafts. It is not a replacement for Cambridge examiner marking. The following limitations apply.
Cannot replicate Cambridge examiner contextual judgement
Cambridge examiners bring years of standardisation training and subject-specific expertise. The AI applies the published criteria consistently but cannot replicate the nuanced judgement that comes from marking thousands of scripts within a specific examination session.
Cannot verify literary quotation accuracy (0475)
For Literature essays, the AI cannot confirm whether a quotation is accurately recalled from the source text. It assesses how quotations are used analytically but not whether they are word-perfect.
Cannot assess response to unseen stimulus material (0500)
Directed Writing requires responding to specific stimulus passages. The AI does not have access to the original stimulus, so it evaluates the quality of writing and register without knowing whether the content accurately addresses the source material.
Cannot assess speaking and listening components
Cambridge IGCSE English includes speaking and listening components that are outside the scope of written essay assessment.
Cannot replace examination marking for summative assessment
AI feedback is a complement to, not a substitute for, Cambridge examiner marking. It is best used as a formative tool during revision and practice.
Scores are indicative, not definitive
Scores provide a useful benchmark for self-assessment and improvement but should not be treated as equivalent to a grade awarded by a Cambridge examiner or predicted by a teacher.
Important: Literature Quotations
For 0475 Literature essays, the AI assesses how textual evidence is integrated and analysed — its relevance, specificity, and analytical deployment — but it cannot verify that quotations are accurately remembered from the source text. Teachers should check quotation accuracy separately.
Data Privacy
Essays processed and discarded
Essays are sent to the AI for analysis and are not stored unless the student explicitly opts to save their work by creating an account.
Not used for AI training
Student essays are not used to train or fine-tune any AI model. The AI provider (Google Gemini) processes the text for the purpose of generating feedback only.
